[0002] Graphene composite prefabricated heating panels are a new type of heating panel that combines graphene materials with other components and features prefabricated construction. The graphene heating panel mainly utilizes the excellent properties of graphene to achieve its heating function. When the chip is powered on, carbon atoms undergo Brownian motion under the influence of the current. The carbon atoms rub and collide with each other, generating heat energy. This heat energy is transferred outward in the form of far-infrared radiation of 8-15μm, thereby achieving the purpose of raising the temperature. It is typically composed of a heating layer, a heat insulation layer, a heat conduction layer, and a protective layer. It can be widely used in floor heating, wall heating, and ceiling heating systems of various buildings such as residences, office buildings, schools, hospitals, and hotels, providing a comfortable and warm indoor environment.

[0003] Chinese patent application number 202221796686.6 discloses a wood-plastic composite graphene composite prefabricated heating wall panel, comprising a rigid door skin panel, a graphene heating plate, and a wood-plastic hollow wall panel stacked in layers. The rigid door skin panel is located on the top layer, and the graphene heating plate is attached to the bottom of the rigid door skin panel, with a power socket provided on it. The wood-plastic hollow wall panel is attached to the bottom of the graphene heating plate, and has a wiring groove corresponding to the power socket. It adopts a three-layer composite technology, and the wall panel does not deform or crack. The middle layer is the graphene heating plate, which is energy-saving and safe. The bottom layer is the wood-plastic hollow wall panel, and the hollow structure has excellent heat insulation effect.

[0004] However, the above-mentioned wood-plastic graphene composite prefabricated heating wall panels have the following problems in actual use: 1. The edges of the three-layer composite structure lack effective protection, which makes it easy for moisture and other substances to corrode the composite panels from the edges, affecting their service life; 2. Temperature monitoring relies on thermosensitive color-changing probes, which have problems such as high cost and complicated installation.

[0005] Therefore, a graphene composite assembled heating plate is proposed to address the above problems. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model forms a protective frame at the edge of the composite board by setting a covering frame, which prevents moisture from entering from the edge and thus avoids water corrosion that would affect the service life.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0032] like Figures 1 to 5 As shown, this utility model provides a graphene composite assembled heating plate, including a composite plate 1, and a covering frame 2 connected to the outer side of the composite plate 1.

[0033] The composite board 1 includes a lower insulating layer 101, which typically uses materials with good thermal insulation properties, such as polystyrene foam board (EPS) or polyurethane foam, to reduce heat loss to the back of the heating plate, improve heat utilization, and provide some insulation. A graphene heating layer 102 is disposed on the insulating layer 101. Made of graphene material, the graphene heating layer 102 is the core component of the heating plate, responsible for converting electrical energy into heat energy. Graphene has extremely high electron mobility and thermal conductivity. The graphene heating layer 102 is equipped with a heat-conducting layer 103, which is generally made of a material with high thermal conductivity, such as aluminum foil or thermally conductive silicone. Its function is to quickly and evenly conduct the heat generated by the graphene heating layer 102 to the surface of the heating plate, thereby improving the heat transfer efficiency. A protective layer 104 is provided on the heat-conducting layer 103. The protective layer 104 is located on the outermost layer of the heating plate and is mainly used to protect the internal structure of the heating plate from the influence of the external environment, such as wear, moisture, and corrosion.

[0034] Specifically, tenons 3 are provided on the front and left sides of the frame 2, and mortises 4 that match the tenons 3 are provided on the back and right sides of the frame 2. The two opposite parts of the heating plate edge are the tenons 3 and mortises 4 that match the size, and the connection between the heating plates is achieved by their interlocking.

[0035] Furthermore, the insulating bottom layer 101 contains a cavity 1011 filled with insulating filler 1012. Air itself is an excellent insulating medium; the cavity 1011 forms an air insulation layer, effectively reducing heat conduction. Further filling with insulating materials such as polystyrene foam, polyurethane foam, or aerogel, which have low thermal conductivity, further prevents heat loss through the insulating bottom layer 101, improving the insulation effect of the heating panel. This allows heat to be more concentrated and transferred to the area requiring heating, reducing heat loss and improving energy efficiency. The cavity 1011 and the filling insulation material can absorb and buffer external impacts to a certain extent, protecting other internal structures of the heating plate and reducing the possibility of damage to the graphene heating layer 102, heat-conducting layer 103, etc., caused by external collisions or vibrations. This improves the durability and reliability of the heating plate. The insulation material usually also has a certain sound insulation performance. Filling the cavity 1011 can effectively block the transmission of sound and reduce the impact of external environmental noise on the heating plate's operating environment. It can also reduce the transmission of some minor noise that may be generated when the heating plate is working.

[0036] Furthermore, the graphene heating layer 102 is connected to a conductive wire 5, and the conductive wire 5 is connected to a conductive connector 6 for energizing the graphene heating layer 102.

[0037] It is worth noting that through holes 7 are provided at the positions corresponding to the frame 2, the conductive wire 5, and the conductive connector 6. The conductive wire 5 and the conductive connector 6 are installed in the through holes 7 to facilitate the transmission of electricity.

[0038] It is worth noting that the protective layer 104 is composed of a wear-resistant coating 1041 and a thermochromic coating 1042 coated on the surface of the heat-conducting layer 103. The wear-resistant coating 1041 and the thermochromic coating 1042 are alternately arranged on the surface of the heat-conducting layer 103. The thermochromic coating 1042 uses the color change characteristics of the thermochromic material to monitor the temperature change of the heating plate, which can achieve the effects of fast response speed, low cost, and simple installation. In addition, the color change can increase the aesthetics of the heating plate when it is used as a wall panel or floor.

[0039] It is worth mentioning that the upper and lower surfaces of the graphene heating layer 102 are respectively bonded to the heat insulation layer 101 and the heat-conducting layer 103 with epoxy resin adhesive. The epoxy resin adhesive has good bonding strength, insulation performance and chemical corrosion resistance, which can ensure that the heat generated by the graphene heating layer 102 is effectively transferred to the heat-conducting layer 103, while ensuring the electrical insulation performance between the two layers.

[0040] Working principle and process: The frame 2 forms a protective layer at the edge of the composite board 1, preventing moisture from entering from the edge and thus avoiding water erosion that could affect the service life. At the same time, the frame 2 can prevent heat loss from the edge, ensuring that heat radiates into the room from the direction of the heat-conducting layer 103. The thermochromic coating 1042 uses the color change characteristics of the thermochromic material to monitor the temperature change of the heating plate, which can achieve fast response, low cost, and simple installation. In addition, the color change can increase the aesthetics of the heating plate when it is used as a wall panel or floor.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
